In mathematics, a moment problem arises as the result of trying to invert the mapping that takes a measure μ to the sequences of moments : More generally, one may consider : for an arbitrary sequence of functions ''M''''n''. == Introduction == In the classical setting, μ is a measure on the real line, and ''M'' is the sequence . In this form the question appears in probability theory, asking whether there is a probability measure having specified mean, variance and so on, and whether it is unique. There are three named classical moment problems: the Hamburger moment problem in which the support of μ is allowed to be the whole real line; the Stieltjes moment problem, for 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「moment problem」の詳細全文を読む スポンサード リンク
